Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The visceral bone in the penis of dogs that partially surrounds the penile portion of the urethra.






2. The vertical portion of the mandible located at its caudal end; site where jaw muscles attach to the mandible.






3. Skull bones that are part of the external bones of the face; these two bones are the most rostral skull bones and contain the upper incisors in all domestic animals except ruminants.






4. The smallest and most medial of the three pairs of bones that make up the pelvis; forms the cranial portion of the floor of the pelvis.






5. Blood cell production; usually occurs in red bone marrow.






6. The cartilaginous joint (amphiarthrosis) that unites the two sides of the mandible at the rostral end in dogs - cats - and cattle.






7. Viscous fluid formed by the lining layer of the joint capsule of a synovial joint; lubricates joint surfaces.






8. A large - rounded articular (joint) surface; examples are found on the distal ends of the humerus and femur.






9. The bones of the carpus; consist of two parallel rows of short bones located between the distal ends of the radius and ulna and the proximal ends of the metacarpal bones.






10. A bone of a digit (finger or toe). Pl. - phalanges.






11. A skull bone that is one of the external bones of the cranium; the caudal - most bone of the skull that forms the atlanto - occipital joint with the first cervical vertebra through the occipital condyles. The large foramen magnum in the occipital bon






12. The bony roof of the mouth; the division between the mouth and the nasal cavity. Made up of portions of the maxillary and palatine bones.






13. A flat articular surface - such as between carpal bones and between the radius and ulna.






14. The front limb.






15. The long bone of the thigh region; it forms the hip joint with the pelvis at its proximal end and the stifle joint with the tibia at its distal end.






16. A beak - shaped process at the proximal end of the trochlear notch of the ulna; when it fails to unite with the ulna - an ununited process can cause the elbow joint to become unstable - leading to lameness.






17. The midline barrier that separates the left and right nasal passages.






18. The hormone secreted by the thyroid gland that prevents the level of caclium in the blood from getting too high.






19. The single - dorsally projecting process of a vertebra.






20. The visceral bone in the heart of cattle that helps support the valves of the heart.






21. A joint in which the bones are united by cartilage; also called an amphiarthrosis. Only a slight rocking motion is permitted between the bones.






22. Incoordination; animals with this make jerky - spastic movements.






23. A spheroidal articular surface on the proximal end of a long bone; present on the proximal ends of the humerus - femur - and rib. Joined to the shaft of the bone by an area that is often narrowed and called the neck.






24. The upper arm; the area of the thoracic limb between the elbow and the shoulder.






25. The second cervical vertebra; it forms the atlantoaxial joint with the first cervical vertebra - the atlas.






26. The joint movement whereby an extremity is moved toward the median plane.






27. One of the three ossicles in the middle ear; also called the stirrup - it is attached to the oval window of the cochlea and is the innermost of the three ossicles.






28. Skull bones that are the bones of the ear; three pair of bones in the middle ear that transmit sound wave vibrations from the tympanic membrane to the inner ear.






29. The most cranial of the three pairs of bones that make up the pelvis; it forms the sacroiliac joint with the sacrum.






30. A bone whose shape does not fit into the long bone - short bone - or flat bone categories. Bones either have characteristics of more than one of the other three shape categories or have a truly irregular shape. Includes vertebrae and sesamoids.






31. The sievelike area of the ethmoid bone through which the many branches of the olfactory nerve pass from the upper portion of the nasal cavity to the olfactory bulbs of the brain.






32. The microscopic - laminated cylinders of bone that make up compact bone. Oriented lengthwise in a long bone - these consist of a central haversian canal surrounded by concentric layers of bone. Osteocytes in their lacunae are present at the junctions






33. The immovable fibrous joints that unite most of the skull bones; also known as synarthroses.






34. One of the two bones (with the ulna) that form the antebrachium - or forearm; usually the main weightbearing bone.






35. Ankle joint or tarsus; joins the tibiotarsus and the tarsometatarsus.






36. The healing tissue between the ends of a fractured bone that is eventually replaced by true bone as the fracture heals.






37. The joint between the femur and the tibia; called the knee joint in humans.






38. The fibrous membrane that lines the hollow interiors of bones.






39. The lay term for the most proximal joint of the equine digit - which is the joint between the large metacarpal or metatarsal and the proximal phalanx. The proximal sesamoid bones are located on the caudal surface of this joint.






40. Skull bones that are external bones of the cranium; form the lateral walls of the cranium - contain the middle and inner ear structures - and are the skull bones that form the temporomandibular joints with the mandible.






41. A space within a skull bone that is an outpouching of a nasal cavity; depending on the species - these are found within the frontal bones - maxillary bones - sphenoid bones - and ethmoid bones.






42. The paranasal sinus in the sphenoid bone; only present in horses.






43. The long - flexible - caudal portion of the dorsal body cavity formed by the adjacent arches of the vertebrae of the spine; it houses and protects the spinal cord.






44. An arthrodial joint in which two flat articular surfaces rock on each other; the carpus is an example.






45. A skull bone that is one of the internal bones of the face; forms part of the nasal septum.






46. The main growth area of a bone developing by endochondral method; areas of bone development that are located in the main portions of the cartilage rod bone templates in the developing fetus.






47. The central canal that runs the length of a haversian system; contains blood vessels - lymph vessels - and nerves that supply and nourish the osteocytes.






48. Process on the cranial end of the second cervical vertebra (axis) that fits into the caudal end of the first cervical vertebra (atlas).






49. The socket portion of the ball - and - socket hip joint; it is formed at the junction of the ilium - ischium - and pubic bones of the pelvis.






50. The large hole in the occipital bone through which the spinal cord exits the skull.
